Improvement in carriage-wheels



UNITED STATES PATENT EFICE.

IMPROVEMENT IN CARRIAGE-WH EELS.

Specification forming part of Letters Patent No. 51,808, dated January 2, 1866.

To all whom it may concern:

Be it known that I, ANDREW J. CURTIs, of West Winterport, in the county ot' Waldo and State of Maine, have invented a new and useful Improvement in Carriage-Wheels; and I do hereby declare the same to be fully described in the following specilication and represented in the accompanying drawings, of whichv Figure l denotes a top view, Fig. 2 a side elevation, and Fig. 3 a vertical and longitudinal section, of a wheel provided with my said invention, the purpose of which is to secure the tire in place and tighten it properly on the rim or felly of the wheel.

In the drawings, A denotes the felly, B B B, Ste., the spokes, G the hub, and D the tire, of a carriage-wheel, they `being arranged together in the ordinary manner, except that at opposite parts of the wheel the felly has placed within it two metallic socket-pieces, E E, made with sockets a a b, two of which in each part E are arranged for the reception of the ends of the wooden part of the I'elly, and the other, b, is for holding a tenon, c, extending from one ofthe spokes. Each of the parts E has apassage, d, formed through it at an acute angle with the tire, such tire at the outer end of the said passage being furnished with a hole, c, for reception of the hooked head of a screwbolt, F, which goes through the passage d, and has a screw, g, and nut h where it projects from the passage d. The nut operates against a shoulder or abutment, fi, extending from the felly and forming part of the socket-piece E.

The two ends of the tire are represented at 7c k, it being a bar of metal bent around in the form of a hoop, and being provided with a hole, Z, which is arranged near to one of its ends 7c k, and formed to receive and tit to the inclined or hooked head of a stud or screw, m, fixed in and so as to project from one of the socket-pieces E, in manner as shown in Figs 1 and 3.

Each passage d should be of a sufcient size to allow ot' all the necessary movements whether lengthwise or otherwise) of its bolt F while in the act of drawing the tire closely on the circumference of the felly.

As many of the socket-pieces E, with their straining bolts and screws, may be applied to or disposed within the i'elly as may be necessary, one being sufcient in many instances, although it will be better to have two or more of them. f

In applying the tire it is to be hooked upon the stud m and the head of the lever-bolt F, after which the nut of the said bolt should be screwed u p against its abutment, so as to cause the bolt to draw closely upon the felly that part ot' the tire which may extend between the bolt and the stud m. N ext the tire should be hooked upon the head f ot' the upper bolt, after which the :nut of such bolt should be screwed up against its abutment, so as to draw the remaining part of the tire closely into place on the felly.

With my invention applied to a Wheel it will be seen that whenever the tire thereof may become loose on the wheel it will be avery easy matter'to tighten it.

rlhe combination and arrangement, substantially as hereinbefore explained, of one or more screw-bolts, F, and the stud Z with a wheelfelly and tire, or with the saine and one or more socket-pieces, E,arranged with respect to the felly substantially as hereinbefore specied.
